There is an Humble
Rhaknar bundle.
You mean real gambling, as in hoping to get a foil card, crafting the right profile background, getting the right loot?
Like
the Hitler emoji?
Or
the Trump emoji?
Or
the heart emoji?
My limited experience was quite bad. Maybe I over-estimated the odds.
Or something more grounded, for which you have reasonable chances of success? Unless one owns a level-up bot*, for which there is a personal cut whenever people exchange cards, gems, keys etc., and for which there is not the 15% market fee, gathering $1,000 in a year sounds unrealistic to me.
* Or a bot network to farm cards during seasonal events.
